LaboratoryHLA-DQA1 unresolved alleles [Type] by High resolution
Definition
HLA unresolved alleles are alleles that have ambiguous typing assignments; it's a way of listing which allele assignments are uncertain relevant to the level of resolution. It has been recommended that reports include all uncertainty in the HLA typing assignment relevant to the level of resolution as stated. As such, this term is intended to report the genotypes and/or alleles that have not been excluded and therefore, should be listed in the report [PMID:22001389]. Due to the variability in reporting and updates, example answer lists are not provided, however, the following resource can provide examples of expected answers- https://www.ebi.ac.uk/ipd/imgt/hla/ambig.html.
